The invention discloses a feeding mechanism for feeding media with different thicknesses, and a medium processing device. The feeding mechanism comprises a plurality of roller assemblies, a plurality of lever pressing arms, a plurality of elastic pieces, and a switch piece; a medium feeding port is formed among the roller assemblies; the level pressing arms are arranged on two sides of one of the roller assemblies; each level pressing arm is provided with a lever body and a roller pressing end and a switch pressing end which are positioned at two ends of the lever body, and the lever body is provided with a supporting point part; the elastic pieces are pressed against the roller pressing ends of the lever pressing arms respectively; and the switch piece presses the switch pressing ends of the level pressing arms movably and selectively. According to the feeding mechanism, the state that the elastic pieces are pressed against or not contacted with the roller assemblies is controlled by mainly using a lever pri
